Isopropyl Myristate (IPM) / آئسوپروپائل مائرسٹیٹ

Isopropyl Myristate is a synthetic ester produced through the esterification of isopropyl alcohol with myristic acid, a saturated fatty acid naturally occurring in coconut and palm kernel oil. First introduced into cosmetic and pharmaceutical formulations in the mid-twentieth century, IPM quickly became a formulation standard due to its exceptional emollient properties, low viscosity, and remarkable compatibility with a wide range of active and aromatic ingredients.

What sets IPM apart from heavier emollients and carrier oils is its dry, skin-sinking texture. Unlike natural oils such as coconut or mineral oil, IPM leaves no greasy residue and is rapidly absorbed into the upper layers of skin. In perfumery, it has earned a distinct role as a non-alcoholic solvent that dissolves and carries aroma chemicals with excellent clarity, making it the preferred diluent in oil-based perfumes, roll-ons, concentrated attars, and beard oils. Its ability to solubilize musks, resins, and high-impact aroma chemicals without haze or separation gives formulators clean, professional results.

Applications & Usage Guidelines

Fine Fragrance 

IPM is widely used in oil-based perfume formats such as roll-ons, solid-to-oil sticks, and concentrated parfum oils. It dissolves most aroma chemicals with excellent clarity and produces a smooth, non-alcoholic finish. It is not typically used in spray EDPs or EDTs where ethanol is the primary carrier.

Attar & Oriental Blending 

IPM is arguably the most important carrier in attar and oil-based perfumery. It thins dense resinous and musky bases without altering their scent profile, ensures uniform blending of heavy materials like oud, ambergris, and sandalwood, and delivers a clean dry-down on skin. Pakistani and Middle Eastern attar traditions rely heavily on IPM as the modern carrier of choice.

Functional Fragrance

In functional applications such as body sprays, deodorant sticks, hair mists, and beard oils, IPM adds emollient value alongside fragrance delivery. It helps the scent adhere to skin and hair while simultaneously conditioning the surface. A practical dual-function ingredient in leave-on personal care formats.

Cosmetics 

IPM is a first-choice emollient for creams, lotions, serums, lip balms, and makeup products. It improves spreadability, reduces drag on skin, and enhances the sensory profile of heavier formulations. It is also commonly used to solubilize oil-soluble actives and give serums a luxurious yet non-greasy feel.

Home Fragrance

IPM can be used in reed diffusers and oil burners as a carrier for fragrance oils, particularly where a slower, more controlled evaporation rate is desired. It is less ideal for candles and wax melts due to its low vapor pressure and potential to affect wax consistency. Functional but secondary to DPG and dipropylene glycol formats in home fragrance.
